INTAKE AIR TEMPERATURE SENSOR
Intake air temperature sensor is built in to the air flow
sensor. Intake air temperature sensor detects intake
air temperature through thermistor's resistance
change and outputs the voltage according to intake
air temperature to engine-ECU. Engine-ECU uses
this output voltage to compensate fuel injection con-
trol and ignition timing control. Sensor properties are
as shown in the figure.
MANIFOLD ABSOLUTE PRESSURE
SENSOR
The manifold absolute pressure sensor is installed in
the inlet manifold. Manifold absolute pressure sensor
uses a piezo resistive semiconductor to output the
voltage according to manifold absolute pressure to
engine-ECU. Engine-ECU uses this output voltage to
compensate fuel injection volume according to mani-
fold absolute pressure. Sensor properties are as
shown in the figure.
